LAK or L.A.K. is an abbreviation for Larry Ass Kickers. Larry Ass Kickers are any tasks that become so difficult as to cause an individual to freeze up, stammer, or skip like a record player. LAKs can also cause paranoia, anger, and frustration. While the origin of LAKs is not exactly known, some psychologists believe that they are triggered by "muffin tops" or "moobs".
Wow! Is because that friggin' vehicle recovery class was a real LAK!
